All lights on front digital are flashing.

Question

hello i have a maytag refridgerator model# MFI2568AEW and serial# 10305650JE. the problem im having is the lights on the front display are flashing and the ice cube flap is constantly opening and closing. i was wondering if this is a simple fix that i can do myself. i am concerned that it might be a computer board that has gone out.
